Description
Nalgene™ sealing closures for Oak Ridge centrifuge tubes are specialised centrifuge tube caps designed to help ensure leakproof performance of Thermo Scientific™ Nalgene™ centrifuge bottles at the recommended maximum permissible speeds. They fit Oak Ridge tube sizes of 28 ml and 30 ml and have a closure size of 20 mm. Manufactured from polypropylene with a red rubber sealing element, the closures are autoclavable and therefore suitable for routine laboratory sterilisation cycles. Each unit is supplied as a case of two pieces, offering a practical spare or replacement option for centrifugation workflows. Belonging to the Nalgene™ product line from manufacturer Thermo Scientific - Laboratory Plastics, these caps are intended for use with 28 ml and 30 ml tubes in research, quality-control and industrial laboratories. The combination of a robust polymer body and elastomer seal supports sample containment during high-speed runs while remaining compatible with standard autoclave protocols. They provide a straightforward way to maintain the integrity of Oak Ridge-format tube systems in everyday laboratory practice.

Questions about Nalgene™ Sealing Caps for Oak Ridge Centrifuge Tubes
What is this article?
Nalgene™ Sealing Caps for Oak Ridge Centrifuge Tubes is the article on this page. Luminix Health distributes Thermo Scientific - Laboratory Plastics for laboratory use. It sits in Screw caps & closures, inside Stoppers, caps & closures, in Labware.
A screw cap has a thread and a liner. The thread has to match the bottle. The liner has to survive the liquid: a pulp liner fails in a solvent that a PTFE-faced liner ignores. The colour of the cap is not the specification.
A closure is the part that decides whether a bottle stays shut and whether the contents attack the seal. A ground-glass stopper matches a ground neck. A screw cap needs the right thread and a liner that survives the liquid. Rubber and silicone stoppers push into a mouth. The liner, not the colour of the cap, is the chemical choice. The vessels they close are indexed under ISO laboratory glassware.
